Temperatures early Saturday morning through early Monday morning are likely to stay below freezing the entire time period. In fact, there is a medium to high chance temperatures stay below 20 degrees all day Saturday, and a medium chance that temperatures fall below 10 degrees early Sunday morning. Temperatures this cold can cause unprotected pipes to burst, harm pets and livestock, kill crops/plants, increase chances of hypothermia and frostbite, and weather-related power outages.
